PAUL AYRES, OF OCEAN SIDE, NEW YORK.

TRAP.

T 0 all whom it may concern:

Be it known that 1, PAUL AYRES, a citizen of the United States, and aresident of Ocean Side, in the county of Nassau and State of New York,have invented a new and Improved Trap, of which the following is a full,clear, and exact description.

The invention relates to plumbers supplies, and its object is to providea new and improved trap, arranged to permit the plumber to quickly andconveniently connect a sink, basin or like fixture with the soil orwaste pipe, and to make a perfect joint with the soil or waste pipe,withoutrequiring the tedious and expensive work of wiping a joint.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claim.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement in the form of an S-trapapplied to connect a sink with the soil pipe; Fig. 2 is a side elevationof the improvement in the form of a P-trap Fig. 3 is a like view of theimprovement in the form of a vented threequarter S-trap; Fig. 4 is asimilar view of the improvement in the form of a running trap; Fig. 5 isa like view of the improvement in the form of a vented running Y-trap;Fig. 6 is a ,similar view of the improvement in the form of a bag trap,and Fig. 7 is an enlarged sectional elevation of the reinforced outletof the trap.

The various kinds of lead pipe traps manufactured and furnished toplumbers for making connection between the soil pipe and a sink, basinor like fixture require the wiping of a joint at the soil pipe, in orderto render the trap safe against leakage of sewer gas into the room orhouse. The connection between the inlet leg of the trap and the sink,basin or like fixture is usually made by flaring out the inlet legterminal of the trap in the collar of the fixture.

In order to avoid the expensive and tedious job of wiping the joint atthe outlet of the trap and the soil pipe, the following arrangement ismade: Each of the traps shown in Figs. 1 to 6, inclusive, has its inletleg A con- Specification of Letters Patent.

nected with the sink, basin or like fixture B in the usual manner, andthe inlet leg A terminates in the double bend or trap proper A, whichleads to the outlet leg A having at its end position a permanent ferruleA of cast iron or other metal harder than lead, the said ferrule beingattached to the outlet leg by spinning the lead of the outlet leg overthe wall of the ferrule A, preferably at the inside thereof, the leadbeing also spun or drawn over the flanged mouth of the ferrule, asplainly shown in Fig. 7.

The diameter of the ferrule A is in excess of the diameter of the leadpipe of which the trap is formed, and when the lead of the end. portionof the outlet leg A is spun against the inside of the wall of theferrule A, then the diameter of the end portion of the outlet leg isincreased and at the same time a continuous lead surface is maintainedthroughout. By providing the out let leg A of the trap with the ferruleA as described, the outlet leg is reinforced, and when the trap isplaced in position its outlet leg can be thoroughly calked. in thereceiving hub of the soil or waste pipe (7, thus insuring the formationof a gas-tight joint at the junction of the trap with the soil or wastepipe C.

By the arrangement described the manufacturer can furnish to the plumbera complete trap having a reinforced outlet leg, thus enabling theplumber to properly connect the soil or waste pipe with the sink,

basin or the like in an inexpensive manner, and within a comparativelyshort time.

It is expressly understood that the traps are manufactured in thevarious shapes and sizes well known in the trade, and each trap isprovided with the reinforcing ferrule as set forth and shown, to permitthe plumber to make a calked joint connection with the waste or soilpipe instead of the expensive wiped joint, as heretofore practiced.

The traps are provided at the bottoms of the bends with the usual screwplugs D for cleaning out purposes and the traps may also be providedwith vents E, as indicated in Figs. 3, 5 and 6.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
